TOOL-HANDLE.

Specification of Letters Patent.

Application led November 23,1915. Serial No. 63,058.

invention relates to tool handles and more particularly to an extension. handle preferably, though not necessarily associated with a pipe wrench. n

The primary object of my invention Iresides in the provision of a slid-able tele-V scopical section for associationk with a stationary, sectionl as well as the novel means on both of the sections for permitting ,the relative adjustment of the sections.

Another object of my invention resides in the provision of a novel means carried by one of the sections. for removably holding the other of the sections in association therewith and preventing accidental displacement thereof.

A still further object of my invention resides in the provision of a deviceof the character described that is simple in construction, eficient inoperation and one that can be manufactured and ket at a minimum cost.y

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection placed on the marwith the accompanying drawings and pointed out in the claims forming a part of this specification.

In the drawings Figure 1 is an elevational view of my invention, the sleeve section being shown in section to illustrate the construction thereof; Fig. 2 is a side elevational View of the handle sections; and Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2 and in' the direction in which the arrow points.

Referring more particularly to the drawings in which similar reference numerals designate like or corresponding parts throughout the different views, I provide a shank 1 threaded adjacent its outer end as illustrated by the numeral 2, the outer terminal of the shank provided with a rigid jaw 3, the threaded portion of the shank being engageable with a sliding jaw 4c operable through the medium of a knurled nut 5y on the threaded portion. It is to be understood that this construction above described forms no essential part of my invention vbeing merely shown and described to illustrate some'of the advantages of my invention The free end of the shank 1 constitutes one section of my'improved handle and it is provided with a plurality of threads 6 for facilitating the maintenance of the sleeve section 7 thereabout and in various adjusted positions thereon. lThe sleeve section 7 is preferably oval shaped in cross section and the inner surfaces of the `long sides adjacentV the end thereof are provided with Vprojections 8. These projections 8 are provided with arcuateAgrooves 9 -of a conguration slightly larger than the thread 6 so that when the sleeved section is associated with the threaded section in such a manner thatV the projections 8 register with the flattened sides 10 of the threadedsection 6, the sleeve section can be slid intoits desired position of adjustment with respect tothe threaded section whereupon the sleeved section 7 can be partially rotated so that the threads 6 will enter the' grooves 9 and maintain the two sections in4 removable adjusted position.

In order to prevent the accidental rdisplacement of the sleeved section from the threaded section, Ihave provided an oval shaped plug 11, the latter havinga longitudinal vopening 12 therein in which is inserted an elongated screw bolt 13, the inner threaded terminal of which is removably engaged in a correspondingly threaded inwardly extending recess 14 in the outer end of the threaded section. As is apparent from the connection shown in the drawings, partial rotation of the plug with respect to the threaded section is permitted during the adjustment and partial rotation of the sleeved section. Likewise the screw bolt can be tightened after adjustment to prevent accidental disengagement of the parts, as will be readily appreciated.

Although I have shown and described the preferred embodiment of my invention, I desire to be understood that I am not to be limited to the exact detailsV shown, however, I desire that great stress be laid upon the peculiar. and novel means for facilitating the sliding adjustment of the sleeved section Patented Jan. 9, 1917.

with respect to the exteriorly threaded section as well as the novel means for preventing accidental displacement of one section from the other.

In practice the invention is particularly useful when a pipe wrench is being used and where a few more inches of leverage is required to adjust the work properly. It lwill be understood that by operating the sleeve section to the outer end of the threaded section, the handle would be long enough to lallow the obtaining of a proper adjustment without encountering the old inconvenience of attaching a pipe tothe handle of a pipe wrench.

From the above description taken in connection with the accompanying drawings, it can easily be seen that I have provided'a device thatis simple in construction, containing but a few simple parts that can be cheaply manufactured and assembled and when assembled can be placed upon the market and sold at a minimum cost.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is :H

1. A handle for tools including a pair of sections, one of which is solid and screw threaded having the opposite sides thereof flattened while the other is hollow and oval shaped in cross section to telescope the solid section, partially threaded projections arranged on oppositesides of the inner bore of thehollow section for removably and adjustably engaging the s olid section, a plug corresponding to the contour of the hollow section, and a threaded bolt passing through the plug and engaging the adjacent end of thesolid section to prevent accidental displacement of the sections and adapted to be tightened to cause the plug to frictionally engage the end of the solid section to positively prevent accidental disengagement of the sections from each other subsequent to adjustment. j j i 2. A handle for tools including an eXteriorly threaded section flattened at diametrically opposite sides, an oval shaped sleeved section for telescoping the threaded section, oppositely arranged projections integral with and extending from the inner sides of the sleeved section adjacent one end thereof, the front faces of the projections being flattened and arranged in uniformly spaced parallel relation with each other and provided with a plurality of uniformly spaced grooves which constitute in effect partially threaded portions, the flattened sides of the threaded section being arranged in close relation with the flattened faces of the projections t and slidable therebetween, the threaded section being rotatable so that the threads will engage the partially threaded portions of the projections, consequently holding the sections in various adjusted positions, an oval shaped plug, and a bolt passing through the plug and engaging the adjacent end'of the eXteriorly threaded section for normally permitting of the partial rotary movementy so that the sections may be adjusted and for preventing disengagement of they sections onefor the other and also adapted to be tightened to cause the plug to frictionally engage with the threaded section to prevent accidental disengagement of the sections, subsequent to adjustment.

In testimony whereof I aiiix my signature in presence of two witnesses.
